Description

Technical Field

[0001] This application relates to the field of automotive air conditioning piping technology, and in particular to a manufacturing equipment for a split coaxial tube outer sleeve for automotive air conditioning piping. Background Technology

[0002] In the automotive air conditioning industry, the coaxial tube, also known as an intermediate heat exchanger, achieves heat exchange by introducing a cold source and a heat source into the inner and outer tubes of the coaxial tube, respectively. The coaxial tube consists of a low-pressure inner tube and a high-pressure outer tube arranged coaxially. The low-pressure gas in the low-pressure inner tube and the high-temperature, high-pressure liquid in the high-pressure outer tube flow in opposite directions, thus forming a pipeline system in which the high and low pressure lines exchange heat independently.

[0003] Reference Figure 1 The outer sleeve 1 has evenly spaced elongated teeth 11 on its inner circumference. The length direction of the elongated teeth 11 is parallel to the axis of the outer sleeve 1. The two ends of the outer sleeve 1 along the axis are provided with bulges 12. The end face of the bulges 12 is provided with flow holes 13. The axis of the flow holes 13 is perpendicular to the axis of the outer sleeve 1. The flow holes 13 penetrate the outer wall of the outer sleeve 1 along their own axis and connect to the inner cavity of the outer sleeve 1. The end of the manifold is welded and fixed to the inner wall of the flow holes 13, and the inner cavity of the manifold is connected to the inner cavity of the outer sleeve 1. When the outer sleeve 1 is fitted around the outer circumference of the low-pressure inner tube, the end face of the elongated teeth 11 presses against the outer wall of the low-pressure inner tube to form a fixed shape. Gas enters from one end of the low-pressure inner tube and exits from the other end. At the same time, liquid in one of the manifolds enters the inner cavity of the high-pressure outer sleeve 1 through the flow hole 13 and exits from the other flow hole 13 into the manifold. The gas flow direction is opposite to the liquid flow direction, thus forming a pipeline system with self-heat exchange between high and low pressure pipelines.

[0004] During the outer tube processing, workers need to grind the long teeth at both ends of the aluminum tube to remove the teeth, and then flare the ends of the aluminum tube after removing the teeth to form a bulge, thus completing the initial processing of the outer tube. The entire outer tube processing process requires workers to repeatedly go through the single process of processing aluminum tubes to form outer tubes, which reduces the production efficiency of the outer tubes and increases the production cost of the outer tubes. Summary of the Invention

[0005] To improve the production efficiency of outer sleeves, this application provides a manufacturing equipment for a split coaxial tube outer sleeve for automotive air conditioning pipes.

[0006] This application provides a manufacturing equipment for a split coaxial tube outer sleeve for automotive air conditioning piping, which adopts the following technical solution:

[0007] A manufacturing equipment for a split coaxial tube outer sleeve for automotive air conditioning piping includes a transport component, a grinding component, and a forming component. The grinding component is used to grind the long teeth at the end of the aluminum tube, the forming component is used to process the end of the aluminum tube to form a bulge, and the transport component is used to transport the aluminum tube from the grinding component to the forming component.

[0008] By adopting the above technical solution, after the grinding component grinds the long teeth at the end of the aluminum tube flat, the transport component clamps the aluminum tube and transports it to the forming component. The forming component processes and shapes the end of the aluminum tube into a bulge. No workers are required to participate in the processing of the outer tube, thereby realizing the automation of the initial processing of the outer tube, improving the processing efficiency of the outer tube, and reducing the production cost of the outer tube.

[0009] Optionally, the forming component includes a fixing member and a forming member. The fixing member is used to limit the end of the aluminum tube, and the forming member is used to upset the end of the aluminum tube to form a bulge. The forming member includes a control member and an upset member. The upset member is connected to the side of the control member facing the fixing member. The control member drives the upset member to move closer to or away from the fixing member. The upset member is used to upset the end of the aluminum tube to form a bulge.

[0010] By adopting the above technical solution, the transport component clamps the aluminum tube on the grinding component and transports it to the forming component. The fixing component presses against the end of the aluminum tube to form a limit, and the forming component processes the end of the aluminum tube to form a bulge, thereby realizing the automated processing of the bulge at the end of the aluminum tube and improving the processing efficiency of the outer tube.

[0011] Optionally, the grinding assembly includes a grinding component and a limiting component. The limiting component is used to limit the end of the aluminum tube, and the grinding component is used to grind the elongated teeth at the end of the aluminum tube. When the end of the aluminum tube is limited to the limiting component, the grinding component grinds the elongated teeth at the end of the aluminum tube.

[0012] By adopting the above technical solution, the limiting component limits the end of the aluminum tube, and the grinding component grinds the long teeth at the end of the aluminum tube flat, thereby achieving the de-toothing process at both ends of the aluminum tube.

[0013] Optionally, it also includes a feeding assembly for storing aluminum tubes, and a transport assembly for clamping the aluminum tubes on the feeding assembly and transporting them to the grinding assembly.

[0014] By adopting the above technical solution, the transport component clamps the aluminum tube on the feeding component and transports it to the grinding component, realizing automatic feeding of aluminum tube processing, further improving the automation of outer tube processing, reducing the workload of workers, and improving the processing efficiency of outer tube.

[0015] Optionally, the feeding assembly includes a feeding rack and a pushing component. The feeding rack has a storage cavity. A limiting block is connected to the end face of the feeding rack facing the transport assembly. A limiting groove is formed on the end face of the limiting block. The inner wall of the limiting groove is used to abut against the outer wall of the aluminum tube portion. The pushing component is connected to the feeding rack. The pushing component is used to drive the aluminum tube in the storage cavity into the limiting groove. The outer wall of the aluminum tube portion abuts against the inner wall of the limiting groove to form a limit. The transport assembly clamps the aluminum tube limited on the limiting block and transports it to the grinding assembly.

[0016] By adopting the above technical solution, the pusher drives the aluminum tube in the storage cavity into the end face of the limiting block. The outer wall of the aluminum tube abuts against the inner wall of the limiting groove, thereby limiting the aluminum tube on the limiting block. The limiting block is located on the side of the feeding rack facing the transport component, so that the transport component can accurately clamp the aluminum tube on the limiting block and transport it to the grinding component, thereby improving the processing efficiency of the outer tube.

[0017] Optionally, the grinding part is connected to an abutment, which is used to position the end of the aluminum tube on the limiting part. The abutment is located on the side of the grinding part facing the limiting part. The distance between the end face of the abutment facing the limiting part and the end face of the limiting part is the tooth removal length of the end of the aluminum tube. The end face of the abutment facing the limiting part is used to abut the end of the aluminum tube.

[0018] By adopting the above technical solution, the distance between the end face of the abutment and the end face of the limiting member is the tooth removal length of the aluminum tube end. When the limiting member limits the end of the aluminum tube, the end face of the aluminum tube abuts the end face of the abutment, so that the tooth removal processing length of the grinding part on the end of the aluminum tube is consistent, improving the accuracy of the outer tube processing and thus improving the processing quality of the outer tube.

[0019] Optionally, it also includes a punching assembly, which is used to process the bulge end face to form a flow hole. The punching assembly includes a punching part and a locking part. The locking part is used to limit the end of the aluminum tube. The punching part is used to process the bulge end face to form a flow hole. The transport assembly clamps the aluminum tube on the forming assembly and transports it to the punching assembly.

[0020] By adopting the above technical solution, the transport component clamps the aluminum tube on the forming component and transports it to the punching component. The locking component limits the end of the aluminum tube, and the punching component processes the bulging end face to form a flow hole, thereby realizing the automated processing of the flow hole of the outer tube, further improving the automation of the outer tube processing and increasing the processing efficiency of the outer tube.

[0021] Optionally, it also includes a grinding assembly, which includes a retaining member and a grinding member. The retaining member is used to limit the outer sleeve, and the grinding member is used to grind the circumferential inner wall of the bulge. The transport assembly clamps the outer sleeve on the punching assembly and transports it to the grinding assembly.

[0022] By adopting the above technical solution, the transport component clamps the outer tube on the punching component and transports it to the grinding component. The retaining component limits the outer tube, and the grinding component grinds the inner wall of the bulge to achieve deburring of the inner wall of the bulge, thereby improving the quality of the outer tube and further improving the automation of the outer tube processing.

[0023] Optionally, it also includes a feeding rack for storing outer sleeves, and the grinding assembly includes a guide ramp for guiding the outer sleeves on the grinding assembly into the feeding rack.

[0024] By adopting the above technical solution, when the grinding part completes the deburring of the inner wall of the bulge, the limiting effect of the consolidating part on the outer tube disappears, and the outer tube enters the unloading rack along the guide inclined plate, realizing the automatic unloading of the outer tube without the need for manual operation by the staff, thereby improving the processing efficiency of the outer tube.

[0025] Optionally, it also includes an oil supply pipe, the oil outlet of which faces between the fixing member and the molded member.

[0026] By adopting the above technical solution, the oil outlet of the oil supply pipeline is located between the fixed part and the molded part. The oil sprayed from the oil supply pipeline lubricates the processing end of the molded part, thereby improving the stability of the molded part in processing the bulge at the end of the outer sleeve.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0039] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0040] This application discloses a manufacturing apparatus for a split coaxial tube outer sleeve for automotive air conditioning piping. (Refer to...) Figure 1 and Figure 2A manufacturing device for a split coaxial tube outer sleeve for automotive air conditioning piping includes a feeding assembly 2, a grinding assembly 3, a forming assembly 4, a punching assembly 5, a smoothing assembly 6, and a transport assembly 7. The feeding assembly 2 stores the aluminum tubes; the grinding assembly 3 grinds the elongated teeth 11 at the ends of the aluminum tubes; the forming assembly 4 forms bulges 12 at the ends of the aluminum tubes; the punching assembly 5 processes the end faces of the bulges 12 to form flow holes 13; and the smoothing assembly 6 removes burrs from the inner walls of the bulges 12. The feeding assembly 2, grinding assembly 3, forming assembly 4, punching assembly 5, and smoothing assembly 6 surround the transport assembly 7. The transport assembly 7 clamps the aluminum tubes and passes them sequentially through the feeding assembly 2, grinding assembly 3, forming assembly 4, punching assembly 5, and smoothing assembly 6.

[0041] Reference Figure 1 and Figure 2 The transport component 7 clamps the aluminum tube on the feeding component 2 and transports it to the grinding component 3. The grinding component 3 grinds and flattens the long teeth 11 at one end of the aluminum tube. The transport component 7 clamps the aluminum tube with the long teeth 11 flattened at one end and rotates it 180° to place the aluminum tube with the other end not flattened on the grinding component 3. The grinding component 3 grinds the long teeth 11 at the end of the aluminum tube to achieve the de-toothing process at both ends of the aluminum tube.

[0042] Reference Figure 1 and Figure 2 The transport component 7 then clamps one end of the aluminum tube with the teeth removed at both ends and places it on the forming component 4. The forming component 4 upsets one end of the aluminum tube to form a bulge 12. The transport component 7 clamps the aluminum tube with the bulge 12 formed at one end and rotates it 180° to place the other end of the aluminum tube without the bulge 12 formed on the forming component 4. The forming component 4 upsets the end of the aluminum tube to form a bulge 12, thus realizing the processing and forming of the bulge 12 at both ends of the aluminum tube.

[0043] Reference Figure 1 and Figure 2 The transport component 7 clamps one end of the aluminum tube with bulges 12 at both ends and places it on the punching component 5. The punching component 5 punches the end face of the bulge 12 to form a flow hole 13. The transport component 7 clamps the aluminum tube with one end punched and rotates it 180° to place the other end of the aluminum tube without punching on the punching component 5. The punching component 5 punches the end face of the bulge 12 to form a flow hole 13, thus completing the initial processing of the outer tube 1.

[0044] Reference Figure 1 and Figure 2 The transport component 7 clamps the pre-processed outer tube 1 and places it on the grinding component 6. The grinding component 6 grinds and removes burrs from the inner walls of the bulges 12 at both ends of the aluminum tube, making the inner wall of the outer tube 1 smooth and flat, thereby improving the production quality of the outer tube 1. It also automates the processing of the outer tube 1 without the need for staff intervention, thereby increasing the production efficiency of the outer tube 1 and thus increasing the production cost of the outer tube 1.

[0045] Reference Figure 2 and Figure 3 The feeding assembly 2 includes a feeding rack 21, a pushing component 22, and an opening and closing component 23. The feeding rack 21 is a strip-shaped rack with a storage cavity 211 for storing aluminum tubes. The storage cavity is connected to the inner wall of the transport assembly 7 with a stepped portion 212. The stepped portion 212 includes multiple upward steps 2121. The upper surface of the step 2121 slopes downward toward the previous step 2121, and the upper surface of the step 2121 is used to abut against the aluminum tube.

[0046] Reference Figure 3 Multiple pushing grooves 2122 are evenly spaced on the side end face of the step 2121. The arrangement direction of the pushing grooves 2122 is parallel to the length direction of the step 2121, and the pushing grooves 2122 penetrate the outer wall of the loading rack 21 in the direction close to the ground. The pushing component 22 includes a pushing hydraulic cylinder 221, a pushing plate 222, and multiple pushing rods 223. The pushing hydraulic cylinder 221 is fixed to the bottom wall of the loading rack 21 by screws, and the axis of the moving end of the pushing hydraulic cylinder 221 is parallel to the length direction of the loading rack 21.

[0047] Reference Figure 3 The push plate 222 is welded and fixed to the moving end of the push hydraulic cylinder 221. One end of each push rod 223 is welded and fixed to the end face of the push plate 222, and the other ends of each push rod 223 face the push grooves 2122 respectively. The axis of the push rod 223 is parallel to the length direction of the feeding rack 21. The push hydraulic cylinder 221 drives the push rod 223 to move closer to or away from the push grooves 2122. The end face of the push rod 223 facing the push groove 2122 is provided with an abutment surface 2231. The inclination direction of the abutment surface 2231 is parallel to the inclination direction of the upper surface of the step 2121, and the abutment surface 2231 is used to abut against the outer wall of the aluminum tube.

[0048] Reference Figure 3 When the aluminum tube is stored in the storage cavity 211, the hydraulic cylinder 221 drives the push rod 223 to slide towards the push groove 2122, the contact surface 2231 abuts against the end face of the aluminum tube and drives the aluminum tube to enter the upper end face of the step 2121 along the side end face of the step 2121, thereby realizing the transportation of the aluminum tube in the storage cavity 211.

[0049] Reference Figure 2 and Figure 3Multiple limiting blocks 8 are evenly welded and fixed to the end face of the loading rack 21 facing the transport component 7. The arrangement direction of the limiting blocks 8 is parallel to the arrangement direction of the pushing groove 2122. A limiting groove 81 is opened on the end face of the limiting block 8, and the upper end face of the step 2121 away from the pushing component 22 faces the limiting groove 81. When the pushing component 22 drives the aluminum tube in the storage cavity 211 to enter the limiting groove 81 along the step 212, the outer wall of the aluminum tube abuts against the inner wall of the limiting groove 81, so that the aluminum tube is limited on the limiting block 8, thereby facilitating the transport component 7 to grasp the aluminum tube.

[0050] Reference Figure 2 and Figure 3 The opening and closing component 23 includes an opening and closing cylinder 231, an opening and closing plate 232, and an opening and closing rod 233. The opening and closing cylinder 231 is fixed to the outer wall of the feeding rack 21 by bolts, and the piston rod axis of the opening and closing cylinder 231 is parallel to the inclination direction of the step portion 212. The opening and closing plate 232 is rotatably connected to the feeding rack 21. The opening and closing plate 232 is located between the step portion 212 and the limiting block 8, and the end face of the opening and closing plate 232 abuts against the upper end face of the step 2121 to separate the step portion 212 from the limiting block 8. One end of the opening and closing rod 233 is welded and fixed to the piston rod of the opening and closing cylinder 231, and the other end of the opening and closing rod 233 is welded and fixed to the rotating shaft of the opening and closing plate 232. When the opening and closing cylinder 231 drives the opening and closing rod 233 to rotate in a direction closer to the opening and closing cylinder 231, it drives the opening and closing plate 232 to rotate in a direction away from the step 212, so that the separation effect of the opening and closing plate 232 between the step 212 and the limiting block 8 disappears.

[0051] Reference Figure 1 and Figure 4 A separate coaxial tube outer sleeve preparation device for automotive air conditioning pipes also includes a base 9, a grinding component 3 and a forming component 4 connected to the end face of the base 9 to form a limit. The grinding component 3 includes a grinding part 31 and a limiting part 32. The grinding part 31 is used to grind the elongated teeth 11 at the end of the aluminum tube, and the limiting part 32 is used to limit the aluminum tube on the base 9.

[0052] Reference Figure 4 The limiting component 32 includes a limiting plate 321, a sliding block 322, a rotating rod 323, and a sliding cylinder 324. One end of the limiting plate 321 is welded and fixed to the end face of the base 9, and the other end of the limiting plate 321 is provided with a limiting arc groove 3211 for the aluminum tube to pass through. The sliding block 322 is slidably connected to the limiting plate 321, and the sliding direction of the sliding block 322 is closer to or farther away from the limiting arc groove 3211. The sliding cylinder 324 is fixed to the limiting plate 321 by screws, and the sliding cylinder 324 is located on the side of the sliding block 322 away from the limiting arc groove 3211.

[0053] Reference Figure 4One end of the rotating rod 323 is rotatably connected to the end face of the sliding block 322, and the other end of the rotating rod 323 is rotatably connected to the end of the piston rod of the sliding cylinder 324. When the aluminum tube is placed in the limiting arc groove 3211, the sliding cylinder 324 drives the rotating rod 323 to rotate towards the limiting arc groove 3211, and drives the sliding block 322 to slide towards the limiting arc groove 3211. The end face of the sliding block 322 abuts against the outer wall of the aluminum tube to form a fixation, and the axis of the aluminum tube coincides with the center line of the limiting arc groove 3211, so that the aluminum tube is not easy to deviate on the inner wall of the limiting arc groove 3211, thereby achieving the fixation of the aluminum tube on the limiting plate 321.

[0054] Reference Figure 2 and Figure 4 The grinding component 31 includes a grinding block 311, a grinding cylinder 312, a grinding motor 313, and a grinding head 314. The grinding block 311 is slidably connected to the end face of the base 9, and the sliding direction of the grinding block 311 is towards or away from the limiting arc groove 3211. The grinding block 311 is located on the side of the limiting plate 321 away from the transport component 7. The grinding cylinder 312 is fixed to the end face of the base 9 by bolts, and the end of the piston rod of the grinding cylinder 312 is welded and fixed to the end face of the grinding block 311 away from the limiting plate 321. The grinding cylinder 312 drives the grinding block 311 to move towards or away from the limiting plate 321.

[0055] Reference Figure 4 The grinding motor 313 is fixed to the end face of the grinding block 311 by bolts, and the axis of the motor shaft of the grinding motor 313 coincides with the center line of the limiting arc groove 3211. The fixed end of the grinding head 314 is coaxially welded and fixed to the motor shaft of the grinding motor 313, and the grinding end of the grinding head 314 faces the limiting arc groove 3211.

[0056] Reference Figure 4 When the aluminum tube is positioned on the inner wall of the limiting arc groove 3211, the axis of the aluminum tube coincides with the axis of the limiting arc groove 3211. The grinding motor 313 drives the grinding block 311 to slide towards the aluminum tube. The grinding end of the grinding head 314 is located in the inner cavity of the aluminum tube, and the axis of the grinding head 314 coincides with the axis of the aluminum tube. The grinding motor 313 drives the grinding head 314 to rotate and grinds the long teeth 11 at the end of the aluminum tube flat, thereby realizing the de-toothing process of the inner wall at the end of the aluminum tube.

[0057] Reference Figure 1 and Figure 4The grinding block 311 is connected to an abutment 10, which is used to position the aluminum tube on the limiting plate 321. The abutment component 10 includes an abutment cylinder 101, an abutment rod 102, and a positioning plate 103. The abutment cylinder 101 is fixed to the grinding block 311 by screws. The piston rod of the abutment cylinder 101 faces the end face of the base 9. The abutment rod 102 is Z-shaped and rotatably connected to the end face of the grinding block 311 in the middle. The rotation axis of the abutment rod 102 is parallel to the piston rod axis of the abutment cylinder 101. One end of the abutment rod 102 is rotatably connected to the end of the piston rod of the abutment cylinder 101, and the other end of the abutment rod 102 is welded and fixed to the positioning plate 103. The positioning plate 103 is located between the grinding block 311 and the limiting plate 321. The end face of the positioning plate 103 facing the limiting plate 321 is used to abut the end of the aluminum tube, and the distance between the end face of the positioning plate 103 and the end face of the limiting plate 321 is the length of the long tooth 11 at the end of the aluminum tube that has been ground flat.

[0058] Reference Figure 1 and Figure 4 When the aluminum tube is embedded in the inner wall of the limiting arc groove 3211, the end of the aluminum tube abuts against the end face of the positioning plate 103. The abutment cylinder 101 drives the abutment rod 102 to rotate towards the base 9, and drives the positioning plate 103 to rotate away from the base 9, so that the abutment effect between the positioning plate 103 and the end of the aluminum tube disappears. The grinding head 314 grinds the long teeth 11 at the end of the aluminum tube, so that the length of the teeth removed by the grinding head 314 at the end of the aluminum tube is consistent, thereby improving the production quality of the outer tube 1.
